Please completely read this operating and installation manual thoroughly prior to connection and
start-up, in particular “Safety Regulations and Appropriate Application”, s. page 10.
Fully automatic battery charger with 2 charging ports for intervention vehicles and special purpose
vehicles, high-quality campers and the marine field.
VOTRONIC chargers of series "Pb SMT" distinguish by their compact design, low weight (high-frequency switching power
supply, Switch Mode Technology), as well as full charging capacity - even in the event of large fluctuations in the power
supply (undervoltage/overvoltage, sine wave form, frequency).
The intelligent microprocessor charging control with charging characteristic lines "IU1oU2oU3" and dynamic charging time
calculation ensures automatic, quick and gentle full charging, as well as subsequent 100 % trickle charge of the connected
batteries from any initial charging state. At the same time, simultaneous supply of 12 V consumers, which are connected in
parallel, is ensured or charging of very large batteries (depending on case of application).
1. Charging Port "

": Selectable Charging Programs Depending on the Type of Battery (Technology), s.
Page 6-7
:
1)
"Lead Acid/AGM 1":
Closed and open
acid/lead-acid-
lead batteries, as well as
AGM "14.4 V"
2)
"AGM 2":
Closed, gas-tight
AGM
batteries (absorbed glass mat)
"14.7 V"
3)
"Gel":
Closed, gas-tight
Gel
batteries, (dryfit, determined electrolyte)
4)
"LiFePO4":
Charging voltage
14.4 V
for lithium LiFePO4 batteries with completely integrated
electronic system balancer and safety circuit (BMS).
5)
Li Storage:
Automatic trickle charging of the LiFePO4 battery when the vehicle is stopped (seasonal
operation) to maintain a charging state of 50-80 %, which is advantageous for the
battery lifetime. Powers also 12 V consumer loads, such as alarm systems,
WLAN etc., as well as the vehicle's starter battery, see
page 5
.
2. Charging Port "
II
":
Separate auxiliary charging port 12 V / 2 A, 3 A for support charging and trickle charging of the vehicle’s starter (lead)
battery with overcharge protection. It can also be used as signalling port for a vehicle engine immobilizer by external
relays, see
page 4
.
Further Characteristics of the Unit:
The
charging voltage
is
free from peaks
and is
controlled in such a way,
that
overcharging
of the batteries
is excluded
.
Fully Automatic Continuous Operation:
The charger may be connected continuously to the battery, thus keeping the
full charge. Battery discharge in case of power failure
is avoided
(separation by safety relay).
Lithium LiFePO4 Auto Wake Up
: Periodical automatic activation of the battery cell balancing BMS.
Battery regeneration in case of extended standstill periods:
twice a week to avoid harmful acid accumulation.
Parallel and Floating Operation:
In case of simultaneous consumption, the battery will either continue to be charged or
maintained via trickle charging. Calculation and control of the adaptation of the charging times is effected automatically
by the charger.
Unattended Charging:
Multiple protection against overload, overheating, overvoltage, short circuit, reverse battery,
incorrect behaviour and back discharge of the battery by electronically controlled gradual reduction down to complete
separation of charger and battery by integrated safety relays.
Connection for
Battery Temperature Sensor
(Accessory Temperature Sensor 825, Order No. 2001):
Lead batteries (acid, gel, AGM): In case of
low outside temperatures
, full charging of the weak battery is
improved
by
automatic adaptation of the charging voltage to the
battery temperature
, and in case of summery temperatures
unnecessary battery gassing
and battery load will be avoided.
For
LiFePO4
batteries, the battery temperature sensor is required:
It serves for battery protection in case of high temperatures or particularly in case of low temperatures below 0 °C.
Silent Run Function:
Noise-optimised operation (night operation) at the touch of a button.
Power Pack Function: Allows supply
of the consumers without battery (such as during battery replacement).
Charging Cable Compensation:
Automatic compensation of voltage losses on the charging cables.
